一种基于氟代电子给体和氟代电子受体的高效有机太阳电池
摘要：
本发明公开了一种基于氟代电子给体和氟代电子受体的高效有机太阳电池，它包括衬底、阴极、阴极修饰层、活性层、阳极修饰层和阳极，其中活性层为氟代电子给体PBDB‑TF和氟代电子受体HF‑PCIC的共混膜。利用HF‑PCIC拓宽的吸收范围和高的电子迁移率，并选择与HF‑PCIC能级匹配和相容性好的氟代电子给体PBDB‑TF，本发明制备的有机太阳电池在保持高的开路电压和填充因子的同时，短路电流密度提高到17.81mA/cm2，能量转换效率(PCE)最高为11.49％，明显优于采用未氟代电子给体和未氟代电子受体的有机太阳电池(PCE＝10.14％)。此外，HF‑PCIC容易合成，有利于降低有机太阳电池的成本。
摘要（英）：

The invention discloses an efficient organic solar cell based on a fluorinated electron donor and a fluorinated electron acceptor. The efficient organic solar cell comprises a substrate, a cathode, acathode modification layer, an active layer, an anode modification layer and an anode, wherein the active layer is a blended membrane of the fluorinated electron donor PBDB-TF and the fluorinated electron acceptor HF-PCIC. The prepared organic solar cell has absorption range broadened by the HF-PCIC and high electron mobility, selects the fluorinated electron donor PBDB-TF which is matched with the HF-PCIC in energy level and has good compatibility with the same, maintains high open-circuit voltage and filling factors, increases short-circuit current density to 17.81 mA/cm2, and has the energyconversion efficiency (PCE) up to 11.49%, thereby being significantly superior to that of an organic solar cell (PCE = 10.14%) adopting a non-fluorinated electron donor and non-fluorinated electron acceptor; in addition, the HF- PCIC is easy to synthesize, thereby being conductive to reducing cost of the organic solar cell.
